摘要
随着卫星测定轨精度的提高,现有测距系统难以满足要求。文中着重介绍了GEO卫星采用三点测距为实现高测距精度的方案,给出了三点测距系统的结构和功能,并分析测距系统模型,以及提高测定轨精度的因素,最后对测距性能进行了分析。
This paper mainly introduces the construction and function of tri-station ranging system for new generation GEO satellite.It analyses the system mathematical model building.The GEO satellite requires higher precision of its orbit measuring,but ranging systems in use cannot match the requirement by now.A spread spectrum ranging system with tri-station is designed,to improve ranging precision.It also present the structure of transmitter onboard,and the composition of ranging station on earth,as well as the protocol of communication.The system performance is analysed in the end.
